I’ve eaten at ‘Ohana 3 times...9:30, 9:50, and 5:15.
The late night experiences were so much better than the earlier one. We’ve always been seated immediately there, but the atmosphere is very different later. It was less crowded and hectic, and they’d stopped the coconut racing, etc. We were very lucky and scored window seats on both of the late night occasions, and had a lovely view of the fireworks. I noticed no difference in the quality of the food.
Enjoy!!
